Roberts, J T; Friend, C M

In this work, the authors report the reactivity of the three sulfur containing heterocycles, namely thiophene, 1, thiophane, 2 and trimethylene sulfide, 3, on clean Mo(110) under ultrahigh vacuum conditions. These studies were undertaken to compare the reactivity of Mo(110) to previously reported work on Mo(100) and to investigate the role of varying the degree of unsaturation and ring size of the reactant molecule in the desulfurization process. Thermal desorption used in conjunction with isotopic exchange is the primary tool used in these investigations. Low energy electron diffraction and Auger electron spectroscopy were also used to monitor surface order and composition, respectively.
